Use disable_non_proxied_udp for webRTCIPHandlingPolicy

Browse source 
The stricter mode `disable_non_proxied_udp` is preferable
to `default_public_interface_only` to prevent local IP
address leakage through WebRTC.

This mode is properly supported since Firefox 70, so the
less strict `default_public_interface_only` will now be
used only for Firefox 69 and older.
